We begin with the candid comments from leah remini. Dan harris has done extensive reporting on the church of scientology. He's here with the story. Good morning, dan. Reporter: Leah remini has spoken selectively and carefully about her departure. But last night on "dancing with the stars," her comments were blunt. In this behind-the-scenes footage aired monday night on "dancing with the stars," leah remini opens up about her bedeparture from the church of scientology is weighing on her. She joined the church at age 7. But then, after what she's described as years of escalating tension and frustration, this summer, she became one of the most high-profile celebrity scientology defectors. Go, go, go. That's okay. Okay. You just started working on this. Okay. Okay. You're all right judging yourself. Leah is really hard on herself. I knew this summer she had a difficult experience. But to the degree it affected her, I had no idea. We're used to everything that happens is our fault. You're used to taking a lot of negativity on yourself. The church is looking for me to fail so they can say to their parishioners, you see what happens when you leave the church? Like they're waiting for me to fail. What will this experience do for you? I think it's going to get me out. You know, out of my head. Out of beating myself up. Out of the bad habits. Reporter: She may have been worried about failing. But the judges loved her samba LAST NIGHT, GIVING HER SOLID 8s. And earning her a standing ovation from the crowd. And a shot to compete again next monday night. Overnight, we reached out to the church of scientology for a comment. And a spokesperson sent us this candid e-mail. We know this may come as a surprise to someone as self-absorbed as ms. Remini, but we could care less if she wins or loses on "dancing with the stars." Until now, the church has been careful on this case. But this may indicate an escalation. A lot of hard feelings on both sides. That's safe to say. Thank you, george.
